Subscription Option - Network User Identification
Subscription Option - Network User Identification override
Enables the DTE to provide information to the network for billing, security
or network management purposes on a per call basis.
This information may be provided by the DTE in the call request packet or
in the call accepted packet. If the network determines that the NUI is invalid
or not present when required by the network, it will clear the call.
The NUI is never transmitted to the remote DTE.
The calling DTE address transmitted to the remote DTE in the address field
should not be inferred from the NUI.

When this facility is subscribed to, one or more NUIs are also agreed. Associated
with each NUI, is a set of subscription-time optional user facilities. When
one of these NUIs is provided in a call request packet, the set of subscription-time
optional user facilities associated with it overrides the facilities which apply
to the interface.

This will normally be used for X.32 but X.25 and X.32 are so similar that I think its worth including here.
UKa say they support this at release 4 but I suspect this requires TAMS *** check ***
